What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionUmbilical cord blood (UCB) contains hematopoietic stem cells with therapeutic potential and unique cellular properties. Due to the limited number of stem cells in the UCB (surrogate marker total nucleated cells, TNC), only one in five donations is suitable for transplantation. The aim of this study was to investigate whether predictive factors exist for a TNC count above the 99th percentile. MATERIAL AND
methodsRetrospective data analysis of the 100 largest donations from 2,299 registered UCB units. Differences between maternal, fetal, and obstetric factors were analyzed and compared with a standardized cohort of 731 registered UCB units.
resultsmaternal age and BMI in the Top100 cohort were higher compared with the comparative cohort (32 vs. 31 years, p=0.007; 30 kg/m2 vs. 29 kg/m2, p=0.024). There were significantly more P1 (76.0 vs. 62.8%, p=0.013) and women with gestational diabetes (5.00 vs. 1.65%, p=0.044). The gestational week, birth weight, the proportion of vaginal-operative deliveries and secondary caesarean sections were higher in the Top100 cohort (40+4 vs. 40+1 wks, p=0.002), (3700 vs. 3450 g, p<0.001), (53.0 vs. 22.7%, p<0.001) (10 vs. 6.2%, p=0.014).
conclusionFor a successful transplant, the amount of TNC in the UCB unit is crucial. Vaginal-operative deliveries, secondary caesarean sections, and a birth weight above 3700 g are favorable with regard to stem cell content. In cases with a complicated course of delivery, collection should not be neglected once the mother and child are safely cared for.
